The product name was chosen to differentiate it from Google Website Optimizer, as my tool makes creating tests super easy.
Leaning the word up against something like GWO seems more like hoping to catch some customers who confuse the two. I know that is probably not what you are doing but it could be interpreted a such and I would stay away from that kind of possible confusion.
If you want it to stand out, call it Wingify. It's not the name that makes the success, it's the product(and the connections and timing etc), but if you want to differentiate your product calling it almost the same isn't going to create anything but confusion.
